Safety apparatus for electric appliances

Abstract

A safety apparatus for electric appliances which includes a sensor for sensing that an electric appliance is operating. An alarm coupled with the sensor, whereby an alarm is initiated. A manually operated alarm disabling switch permitting a person supervising the operation of the electric appliance to temporarily disable the alarm for a predetermined time interval.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 
     
       1. A safety apparatus for electric appliances, comprising: sensing means for sensing that an electric appliance is operating:   auditory alarm means coupled with the sensing means, whereby said alarm is initiated upon the electric appliance operating, the alarm continuing as long as the electric appliance continues to operate; and   alarm disabling means for disabling the alarm means for a predetermined time interval while the electric appliance is operating, the alarm disabling means having a reset switch whereby the predetermined time interval is restarted.   
     
     
       2. A safety apparatus for electric appliances, comprising: sensing means for sensing that an electric appliance is operating;   an auditory alarm means coupled with the sensing means, whereby said alarm is initiated upon the electric appliance operating;   alarm disabling means for disabling the alarm means for a first predetermined time interval while the electric appliance is operating, the alarm disabling means having a reset switch whereby the first predetermined time interval is restarted; and   switch means for turning off the electric appliance should the alarm disabling means not be reset within a second predetermined time interval.   
     
     
       3. The safety apparatus for electric appliances as defined in claim 2, wherein the sensing means senses power consumption of the electric appliance. 
     
     
       4. The safety apparatus for electric appliances as defined in claim 3, wherein power consumption is monitored by sensing one of current and voltage. 
     
     
       5. The safety apparatus for electric appliances as defined in claim 2, wherein the alarm is audible. 
     
     
       6. A safety apparatus for electric appliances, comprising: a power consumption sensor;   an audible alarm coupled with the sensor, whereby an audible alarm tone is initiated upon the electric appliance operating;   alarm disabling means for disabling the alarm for a predetermined time interval, the alarm disabling means having a manual reset switch whereby a person supervising the operation of the electric appliance restarts the predetermined time interval; and   switch means for turning off the electric appliance should the alarm disabling means not be reset within a second predetermined time interval.   
     
     
       7. A safety apparatus for electric appliances, comprising: a plug adaptor having a male portion adapted for insertion into a residential electric outlet and a female portion adapted to receive the plug from an electric appliance;   a power consumption sensor being electrically coupled with the plug adaptor, whereby power consumption by the electric appliance is monitored;   an audible alarm coupled with the sensor, whereby an audible alarm tone is initiated upon the electric appliance operating;   alarm disabling means for disabling the alarm for a predetermined time interval, the alarm disabling means having a manual reset switch whereby a person supervising the operation of the electric appliance restarts the predetermined time interval; and   switch means for turning off the electric appliance should the alarm disabling means not be reset within a second predetermined time interval.
